Data recovery is the process of retrieving lost or deleted data from computers or storage devices. Data loss can occur for many reasons, such as

Deletion

• Accidental or intentional deletion of data.

Format

• Formatting a storage device can result in the loss of all data on it.

Physical damage

• The storage device has a physical problem, for example, a faulty hard drive.

File system damage

• Corruption of the file system can prevent access to data.

Virus or malware

• Computer viruses or malware can damage data.

Data recovery is usually done through professional data recovery services or software. Here is a general data recovery process:

Evaluation

• An expert or software is used to determine the cause of data loss and assess recoverability.

Physical control

• If data loss is caused by a physical problem, the storage device is physically checked.

Recovery

• The recovery process is initiated and necessary steps are taken to recover the data.

Repair and copy

• The recovered data is repaired and copied to a new storage medium.

Control and Verification

• The integrity of the recovered data is checked and verification is performed.

Delivery

• The recovered data is delivered to the customer.

One important thing to remember is that there is no guarantee how successful data recovery will be, so it is important to practice regular backup habits to avoid data loss.
